i use cj daily fix most days, cj gentle cleansing shampoo (low poo) about once every 4 days.
you need to scrub your scalp whatever you use to clean, that is where the dirt/sebum/etc. is building up. if you feel you have some product buildup, then also GENTLY massage your hair.

everyone's hair is different so you have to find what makes your hair happy. trial and error.
